The Grant Building, one of the downtown skyscrapers in Pittsburgh has an aviation beacon that instead of flashing at regular intervals, was set up to flash in Morse code the letters that spell "Pittsburgh".

This year, Tom Stepleton, a recreational pilot familiar with Morse code noticed that the letters transmitted by the beacon spelled... "PITETSBKRRH."

The one-minute video clip above shows the sequence. The city has tried to fix the problem, but after the first attempt, the beacon is now flashing ... "TPEBTSAURGH."
